Accepting 2024 seed orders but also harvesting and processing seeds so there may be some delays in shipping!
Avena Strigosa has blue-green upright plants. The small black-hulled seeds weigh about 1.5g/100seeds. It is a historical crop of marginal soils that has largely disappeared but is still grown in the islands off Scotland, generally in mixtures with rye and Bere barley. It is used mostly for animal feed but also human consumption, thatching, and crafts.
